IMPROVED LABORATORY TRANSITION PROBABILITIES FOR Hf ii AND HAFNIUM ABUNDANCES IN THE SUN AND 10 METAL-POOR STARS
Radiative lifetimes from laser-induced fluorescence measurements, accurate to 5%, are reported for 41 oddparity levels of Hf ii. The lifetimes are combined with branching fractions measured using Fourier transform spectrometry to determine transition probabilities for 150 lines of Hf ii. Approximately half of these new transition probabilities overlap with recent independent measurements using ...
متن کاملComment on “Oxidation of Hafnium and Diffusion of Hafnium Atoms
In his paper, Chandi C. Dey reports on the measurement of the nuclear quadrupole interaction of 181Hf(β−)181Ta in α-Hf metal with a few percent zirconium heated in air by perturbed angular correlation (PAC) of γ-rays. Since he did not observe the formation of HfO2 up to 773 K and during initial heating at 873 K for one day, he concluded that no oxygen is absorbed. The time dependent hyperfine i...

Tositumomab and iodine I 131 tositumomab (Bexaar) therapeutic regimen targets monoclonal antibodies against the CD20 antigen expressed in non-Hodgkin lymphoma. This article reviews the mechanism of action and clinical indications for this regimen.
متن کاملMagnetism in hafnium dioxide
Thin films of HfO2 produced by pulsed-laser deposition on sapphire, yttria-stabilized zirconia, or silicon substrates show ferromagnetic magnetization curves with little hysteresis and extrapolated Curie temperatures far in excess of 400 K. The moment does not scale with film thickness, but in terms of substrate area it is typically in the range 150–400 B nm −2. The magnetization exhibits a rem...
متن کاملHafnium germanium telluride
The title hafnium germanium telluride, HfGeTe(4), has been synthesized by the use of a halide flux and structurally characterized by X-ray diffraction. HfGeTe(4) is isostructural with stoichiometric ZrGeTe(4) and the Hf site in this compound is also fully occupied. The crystal structure of HfGeTe(4) adopts a two-dimensional layered structure, each layer being composed of two unique one-dimensio...
